After taking herbal decoctions for a cold injury (Shanghan), diarrhea persists, accompanied by fullness and hardness in the epigastrium. The Xie Xin Tang (Drain the Epigastrium Decoction) was administered. Subsequently, other purgative medicines were used, yet the diarrhea did not cease. The physician treated it with Lizhong Tang (Regulate the Middle Decoction), but the diarrhea worsened. Since Lizhong Tang treats disorders of the Middle Jiao (Middle Burner), and this diarrhea is located in the Lower Jiao (Lower Burner), the following formula should be used:

Yu Yu Liang (Magnetitum) and Chi Shi Zhi (Halloysitum Rubrum) (each 1 jin, crushed).
Take the above two ingredients, add six sheng of water, boil to obtain two sheng of liquid, and divide into three doses. If the diarrhea persists after administration, promote urination to stop the diarrhea.

Formula for treating pus and blood in stool after cold injury:
Ejiao (Donkey-hide Gelatin) (1 liang), Huang Bo (Phellodendri Cortex) (2 liang), Huang Lian (Coptidis Rhizoma) (4 liang), Zhi Zi Ren (Gardeniae Semen) (14 seeds).
Take the above four ingredients, crush them, add six sheng of water, boil to obtain two sheng of liquid, remove the dregs, add Ejiao, and continue boiling until dissolved. Divide into three doses. (The formula in *Jia Yi Jing* does not contain Huang Bo, but contains Huang Qin (Scutellariae Radix)).

Process and mix the above six ingredients. Take a mulberry branch about three cun long like an arrow shaft, wrap two cun of its head with cotton, moisten the cotton tip with saliva, apply the medicine onto the cotton, and insert it into the anus. Leave it for half a day, then replace it. Apply twice daily; this yields miraculous results.
